Yup....that's what I figured you were doing which was why I saw a problem
with the for loops having $i being incremented by more than one (ex. $i +
20). In order for that to have worked more effectively you would have
needed to multiple $num_pages by 20 as well before the for loop was called
which was redundant....and probably would have caused problems with getting
the proper results from the database depending on how you coded it.
